I'd like to give them laxatives and take away the loo roll, deprive the smokers of cigarettes...maybe give the non-smokers the ciggies and tell them they have to ration them and decide who most needs one. Make them have really unusual food for the evening, maybe some deep fried bugs, or snake blood. I'd like for them to be given random tabloid headlines, but not be told who they are about. I think they should be told on Monday that the task for Saturday is to memorise a string of numbers/objects, then come Saturday change the task to a dance mat challenge.
